How to access AUX port on ASR?

[Svante Bolander]

I am trying to use the AUX port on a ASR 1002 to connect to a console port on another router. Usually you telnet to port 2000+line number and then you are on the AUX with an outgoing connection. But I can not figure out how to do this on ASR. I am running 3.2S. Telnetting to port 2001, AUX is line 1, makes the router to send RST back. It seems that TCP is not listening on that port at all.

Anyone using the AUX port on ASR?

transport output all

Thanks, that made it to work. Actually, I found out that the minimum config on AUX is

line aux 0
transport input all
transport output none
stopbits 1

Authentication is handled through aaa new-model.

Hi,

We are new with Cisco ASR and IOS XR.
Our new WAN Router is an ASR 9001.

But I do not get the aux configuration.

RP/0/RSP0/CPU0:ro04000230_iWAN_ITZ(config)#line ?
console console template
default default template
template user defined template

there is no "aux"...

And if i enter "line aux" or "line aux 0", it looks like the XR interprets it as an user definded template, and i can't configure aux parameters:

RP/0/RSP0/CPU0:ro04000230_iWAN_ITZ(config-line)#exit
RP/0/RSP0/CPU0:ro04000230_iWAN_ITZ(config)#line aux 0
RP/0/RSP0/CPU0:ro04000230_iWAN_ITZ(config-line)#?

I want to use the aux port for telnet hopping like i did on ISR G2:

line aux 0
session-timeout 30 output
exec-timeout 60 0
no exec
transport input all
telnet break-on-ip
stopbits 1
speed 9600
flowcontrol hardware
exit

Do anyone knows how to configure the aux port for outgoing connections?

Thanks a lot!
